Starting in 1935, the Italian Fascist government had eliminated the division of roles and responsibilities at the highest level of the armed forces by nominating Benito Mussolini minister or the Army, Air Force and Navy and thus giving him total control over these institutions.

“Palazzo Marina’

The highest hierarchy within the Navy which used to be called “Ufficio del Capo di S.M.” was renamed in 1936 “Ufficio di Stato Maggiore” (High Command Office) and was organized in three units:

  • Information (I)
  • Operations and Training (OA)
  • Mobilization, Defense, Services (MDS)

And four inspectorates:

  • Artillery and ammunitions (IAM)
  • Submarine Weapons (IAS)
  • Naval Engineering (ISGN)
  • Naval aviation (IAV)
  • Historical Bureau and Procurement

All units and inspectorates were led by an admiral with the sole exception of Naval Aviation which was under the command of a general from the air force.  As early as 1938, when a looming war against the British Empire appeared inevitable, the 1st Office (Operations and War Plan) was reorganized in what was a precursor of SUPERMARINA. Before the beginning of the conflict, in May 1940, the government decreed a reorganization of the Navy command into:

  • Operational Group (SUPERMARINA)
  • Units and Inspectorates (MARISTAT)

Specifically, SUPERMARINA responsibilities were defines as:

  • Give general directive regarding naval warfare.
  • Issue general operational orders.
  • Disseminate information regarding naval activity
  • Disseminate information regarding enemy naval activity.
  • Designate the commanding officer at sea.
  • Coordinate the strategic activities at sea of detached units.
  • Promote, under established rules, the participation of ARMERA (independent air force), Italian North Africa High Command (A.S.I.), and the Aegean High Command for both activities organized by itself and or emergencies.
  • Promote, based on individual or ongoing  agreement s, the participation of the allied air force (Germans)

SUPERMARINA included as part of its operation group:

  • The Chief of Naval Operations along with his flag officer and designated personnel
  • The Vice Chief of Naval Operations along with his flag officer and designated personnel
  • Four assisting admirals along with their flag officer and designated personnel divided in
    • Head Operation unit.
    • Head plans and operations.
    • Officers assigned to the “Comando Supremo” office.

SUPERMARINA was the telegraphic denomination for this office, and, during the conflict, it quickly became a household name due to the many mentions in war bulletins. SUPERMARINA operated, more or less, in the same manner during the whole conflict. Shifts lasted 12 hours and the change of officer on duty took place at 8:00 PM and 8:00 AM.  After the morning change of guard, a small report was presented to the new officer and forwarded to the head of the Navy and also ‘Comando Supremo’. At 11:30 AM all admirals met under the presidency of the Vice Chief of Naval Operations (Adm. Edoardo Somigli until December 10th, 1940 and then Adm. Inigo Campioni, and eventually Adm. Luigi Sansonetti) to review the situation and issue orders which had to be approved by the Chief of Naval Operations  .

Naval operations, including the position of ships, were tracked on a very large map of the Mediterranean though the use of push pins (some authors refer to ship cutouts).  Each type of unit was represented by a different type of pin. If the precise position of the units were not known, a new position was estimated based on previous direction and speed. The positions were regularly updated and included know enemy and neutral vessels.

This operational center was located within the building which still houses the Ministry of the Navy along ‘Lungotevere Flaminio” (Along the river – Tiber- in the Flaminio neighborhood).  In addition to the primary area, the Navy had constructed a secondary one in the basement in expectation of aerial bombardment which never materialized. In fact, the ministry was too close to the Vatican to even consider such a reckless action.  When Rome was declared an open city (August 14th, 1943), SUPERMARINA was relocated in Santa Rosa (La Storta) where the Italian Navy hosted its radiotelegraphy operation center located in subterranean bunkers.

This new temporary command center was only 20 km north of the city along the ancient Cassia road and was temporarily housed above ground in specially built barracks.  This office closed definitively on September 12th following the Italian surrender. By then, although it had lost its operational functions, it was the only functioning Italian high military command post having similar organizations, SUPERAEREO and SUPERESERCITO, already disbanded.

Throughout the conflict, SUPERMARINA was directly in control of most naval operations in line with Italian military naval doctrine which called for a highly centralized command post.  Lack of operational freedom for the commander at sea was often the reason for a very conservative conduct and, as in the case of Matapan, resulted in terrible losses. SUPERMARINA, despite the capillary organization, lacked the intelligence insight the Royal Navy and the direct line of communication and collaboration with both the other branches and the German allies.  To overcome this last deficiency, SUPERMARINA positioned German coordination officers aboard the larger units of the Italian fleet.

R. Smg. Macallè

The Macallé was an Adua-class, 600 series, Bernardis type submarine. Laid down on March 1st, 1936, in the OTO shipyard in La Spezia, it was launched on October 29th, 1936, and delivered to the Regia Marina on March 1st, 1937.

The beautiful shape of hull of the 600 series. Here the Macallè still on the slip in La Spezia.

On April 20th, 1937, the Macallé was assigned to the 23rd Submarine Squadron based in Naples. After undergoing a brief training, from August 27th through September 3rd, 1937, the submarine carried a special secret mission in connection with the operations of the Spanish Civil War.

The Macallè leaving Mar Piccolo, Tranto
(Risolio Collection)

In 1938, the Macallè was reassigned to La Spezia first under the command of Lieutenant Commander Giuseppe Aicardi and then Lieutenant Commander Salvatore Todaro. Transferred to the submarine base of Mar Piccolo in Taranto, on November 14th, 1938 left for Leros (Italian Dodecanese) arriving on the 16th, and then staying there for a few months. The boat eventually left Leros on March 28th, 1939, and returned to Taranto on March 30th, 1939.

In early 1940, it was reassigned to Massawa, Italian Eritrea, to became part of the 82nd Squadron (VIII Submarine Group) of the Red Sea Flotilla. On June 10th, 1940, in the afternoon, she left Massawa under command of Lieutenant Commander Dante Morone to begin her first war patrol and operate in an area about eight miles east of the British Port Sudan.

During the patrol, the boat ran into many problems. First, due to an overcast sky, the crew couldn’t establish positioning based on celestial navigation. Second, it was difficult to clearly identify landmarks which made navigation in an area known for the many islets, outcropping rocks, shoals, and reefs quite perilous. The more serious problem started manifesting on the 12th when the crew began experiencing symptoms common to food poisoning without understanding that the real cause was methyl chloride leaking from the air conditioning system.

The itinerary

The primary target of methyl chloride (also known as chloromethane) is the central nervous system, with behavioral symptoms and neurologic effects. Overexposures can result in loss of equilibrium, dizziness, semiconsciousness, and delayed death; all the officers and almost all the crew were intoxicated, and there were some cases of madness and delirium.  Although discovered and commercialized since 1928, Freon was not used on Italian submarines until 1940 when boats, such as the Archimede, were refitted replacing chloromethane with freon,

On 14th June, at dawn, a lighthouse was sighted believed to be the Sanganeb Shallows (Sanganeb Reef Light), but it was indeed the Hindi Gider lighthouse, which was about 30 miles away from the assumed position.  This lighthouse is halfway between Port Sudan and Sawakin, about 35 nautical miles off the mainland coast. This mistake caused the loss of the Macallè because the navigation officer believed that the submarine had reached deeper waters, when in fact the unit was still in a danger zone. Quite off course, the Macallè ran aground on the rocks of the island Bar Mùsa Kebir (19°12′ N, 38°11′ E) in the early hours of June 15th. The boat ended up listed nearly 90° on one side, with the bow completely out of the water and the stern submerged.

The heavily intoxicated and non-essential personnel were disembarked on the nearby islet, Barra Musa Kebir, along with supplies and other items, while Captain Morone and some of the others tried to disentangle the submarine. It was not possible. At that point, the secret cyphers were destroyed, and scuttling maneuvers started to avoid the capture of the unit (which was close to territories controlled by the British). The Macallè, weighed down by the water taken aboard, dislodged itself and sank sliding on a seabed of 400 meters. According to other sources, however, the submarine did not sink intentionally, but was lost accidentally during the maneuvers to free it.

Captain Morone, however, forgot (probably due to the numbness produced by the intoxication), to send a distress signal to base (according to other sources the order was given before the sinking, but the radio room was already flooded). The crew of the submarine thus found themselves isolated on a minis ule desert island, with scarce supplies of food and without the base having any idea not only of where they were, but not even knowing that the Macallè had been lost.

Preparations were therefore made for a long stay. Shelters were prepared to avoid standing under the scorching sun and provisions were rationed. Since surviving on the islet for a long time would have been impossible, and the best prospect was capture by the British, it was decided that some volunteers would try to reach an Italian outpost on the coast of Eritrea to set rescue efforts in motion.

On the June 15th, in the evening, three men – Ensign Elio Sandroni, Helmsman Sergeant Reginaldo Torchia, and sailor Paolo Costagliola – boarded a small sailing boat equipped with two oars, with three bottles of water and small quantities of ham and crackers. On the 17th, they landed on the coast of Sudan, but, as it was British territory, they had to move on. On June 20th, they finally arrived at the Italian lighthouse at Taclai, Eritrea, and were able to alert the Navy command in Massawa.

A book (in Italia) dedicated to Elio Sandroni who continued in the Italian Navy to retire as a Rear-Admiral. He passed away in 2012. After saving the crew of the Macallè with a daring feat, he joined the crew of the submarine Perla. On the eve of the Italian defeat in East Africa, the Perla departed on March 1st arriving in Bordeaux on May 20th, 1941, after having circumnavigated the African continent.

An aircraft sent from Massawa parachuted on the islet food supplies and at the same time the submarine Guglielmotti set sail from that base. On June 22nd, the Guglielmotti rescued the crew of the Macallè. The survivors of the Macallè are in very poor conditions, especially as a result of methyl chloride poisoning. Many, as soon as they spotted the Guglielmotti approaching and putting a boat in the water, jumped into the sea and swam to it, not being able to wait any longer. With two or three trips of the boat, the Guglielmotti was able to recover all the survivors. It then moved away and dove (later it would resurface), just as two British planes had returned circling over the island (another aircraft had already done so before). Some of the survivors, mad or delirious from the combined effect of methyl chloride, sunstroke, and thirst, were tied up for the entire journey back to Massawa.

Sub-Chief Torpedoman Carlo Acefalo

One of the crew members, the sub-chief Carlo Acefalo, already heavily intoxicated by the methyl chloride, and debilitated by the trying experience, died on the islet on June 17th and was buried there: he was the only victim among 45 crewmen of the submarine. Ensign Sandroni received the Silver Medal for Military Valor for is valiant effort in seeking help. In 2014 a team was set up to find and recognize the remains of the fallen sailor. The remains of Carlo Acefalo returned to Rome on October 8th, 2018, and on November 23rd, to Savona. The same afternoon the box was transferred to the Town Hall of Castiglione Falletto, in the hall of the City Council. On Saturday, November 24th, in the morning, prayers and the blessing of the remains preceded the burial in the local cemetery, next to his mother Francesca. Carlo Acefalo had returned home after more than 78 years.

In that first and last was patrol the Macallè had traveled 450 miles, all on the surface.

R. Smg. Argento

The Argento was a Class Platino (also known as “Metalli”, or metals), “600” series, Type Bernardis coastal submarine (displacement of 712 tons on the surface and 865 tons submerged). Laid down at the Tosi shipyard of Taranto on April 30th, 1941, it did not enter service until May 16th, 1942. Lieutenant Commander Giuseppe Vocaturo assumed command until July of the same year proving for initial crew training.

In September, 1942, the boat was sent out on its first war patrol, along with the Nichelio, under the command of Lieutenant  Giovanni Tarabini Castellani. The boat reached the assigned patrol area south of the Balearic Island where it remained until October 11th. Upon returning, it sighted two units estimated to be corvettes which could not be attacked since the Argento itself had been probably been spotted.

Another patrol followed in November when the Argento was deployed as part of a barrage of 16 submarines to contrast the Allies’ landing in North Africa near the Algerian coastline. The boat remained in the originally assigned area (B) until the 11th. On the 14th, it penetrated the Philippeville’s outer harbor, however it was not able to engage any target.   On the 18th, the boat was ordered back to base.


Engine repaired, the boat under the command of Lieutenant Renato Frascolla was again on patrol reaching the assigned area on January 22nd along with the Dandolo to contrast Operation Torch. The assigned area, between Cape Carbon and Cape Bougaroni, was already being patrolled by the Avorio and Malachite. The night of the 21st, the Argento was attacked by an enemy aircraft that attempted to strife the boat many a times, but it was repelled by the fire of the boat’s Breda antiaircraft guns. Soon after, at 04:00 AM of the 22nd, in position 37°58’N, 06°15’E, another aerial attack followed and it included the dropping of bombs. This time, the enemy aircraft, repeatedly hit by the Bredas, was seen catching fire and crashing. On the 24th, the boat was ordered back to base.

In February, the Argento was again sent out on patrol to fill in the gap left by the sinking of the Asteria which, on the 17th, had fallen victim of H.M.S. Easton. On the 18th, a convoy was sighted but the Argento could not attack.

In April, the boat was deployed as part of a barrage extending 80 miles along the 08°E meridian, between 38°40’N and 40°00’N. The barrage included the Brin, Platino, and Giada. However, that area did not see any enemy activity.

The Argento in port

In June, the boat was off the Algerian coastline arriving on the 20th positioning itself near the Island of La Galite. The night of the 30th, the boat entered the outer harbor of Philippeville without conducting any mentionable action.

In July, starting on the 11th, the Argento was assigned to a barrage composed of 8 boats stretching from Cape de Fer and the Island of S. Antioco (Sardinia) along the 07°30E meridian.  However, a breakdown forced the vessel back to base. Issue solved, the boat was again on patrol to contrast traffic from Sirte and Malta to Sicily. On the 23rd, while crossing the Strait of Messina, it was targeted by an enemy submarine with the launched of three torpedoes which were skillfully avoided.

With Operation Husky – the landing in Sicily – fully underway the Argento was moved from south of Catania to the southern part of Sicily possibly reaching all the way to the Gulf of Sirte. Without having been able to sight any enemy traffic, the commanding office, Lieutenant Leo Masina, began the return voyage to base. On August 2nd, at around 10:55 PM, while navigating on the surface about 5 miles off the Island of Pantelleria, a destroyer and three other units were sighted at a very short distance.

USS Buck (DD420)

Seeking shelter in the depths of the sea, the Argento was immediately targeted by an intense drop of depth charges some of which caused serious damage. The resistant hull was compromised, and water started entering the boat.  Forced to the surface, the Argento was immediately targeted by intense gunfire and thus scuttling procedures were hastened. The American destroyer USS Buck (DD-420) rescued most of the crewmembers; a few had died during the attack.  The Argento dove one final time at around 00:30 Am of August 3rd reaching its resting place.

USS Buck glory would last only a few weeks, until October 9th, 1943, when it fell victim of U-616 off Salerno.

R. Smg. Antonio Sciesa

The Antonio Sciesa was a boat of the Balilla class built by the OTO shipyard of La Spezia and delivered to the Regia Marina on April 29th, 1929.

La Spezia: the “Sciesa” and “Toti” return to base after completing the African circumnavigation

On 14 September 1933, along with her twin boat Toti, the Sciesa departed La Spezia under the command of Lieutenant Commander Carlo Savio for a demonstrative cruise through the Suez Canal to the Red Sea and continuing with the circumnavigation of Africa and then returning to the Mediterranean Sea through the Strait of Gibraltar.

November 1933: submarines Toti and Sciesa at anchor in Dar es Salaam during the African circumnavigation mission ℗

The purpose of the trip was to verify the performance of these units in warm waters. The submarines stopped at Port Said, Massawa, Aden, Mogadishu, Chisimaio, Mombasa, Zanzibar, Dar es Salaam, Diego Suarez, Lourenço Marques, Durban, Cape Town, Walvis Bay, Lobito, São Tomé, Takoradi, Dakar, Porto Praia, Las Palmas, Gibraltar, and Barcelona, finally arriving at their destination on February 25th, 1934, with good overall performances.

In November 1936 it was one of the first Italian submarines sent clandestinely to support Franco’s forces in the Spanish war, however it did not achieve any results.

On Italy’s entry into World War II on June 10th, 1940, it was sent on an offensive mission off the port of Kotor, returning on June 21st, 1940. On 9 July 9th, she lay in wait north of Cape Passero, returning to base two days later.

On 14 August, it departed Augusta for a patrol off the North African coast, but two days later she had to abort her mission due to a breakdown and headed to Brindisi for repairs.

On 12 December it was sent north of the mouth of the Nile and six days later detected the sounds of other ships on the hydrophone but failed to spot them; The mission ended on December 21st.

In March 1941 she was under repairs up until May 1942.

On June 1st, 1942, the Sciesa returned to operational duties, with Lieutenant Raul Galletti as the commanding officer. It was assigned, along with many other submarines, to transport missions to Libya.

On June 29th, 1942, it left Taranto with 64 tons of fuel and 4 tons of provisions destined for Marsa el Hilal where it arrived on July 3rd.

On July 24th, 1942, it left Taranto with a cargo of 71.6 tons of supplies and gasoline bound for Tobruk arriving at her destination four days later, unloaded the cargo and departed the next day, arriving back in Taranto on August 3rd.

On August 19th, 1942, it again left Taranto to transport 73 tons of food and ammunition to Benghazi arriving at the Libyan base on the 22nd and departing the same day after unloading the cargo, returning to Taranto on August 26th.

On October 1st, 1942, it left again Taranto, bound for Benghazi with 71.9 tons of provisions, ammunition and money from the Bank of Italy arriving in Benghazi on the 5th, unloading the materials and leaving the same day. The following day, at 9.15 PM, the boat launched a torpedo against a submarine spotted on the surface and apparently stationary, hearing a loud explosion and therefore believing that he had hit and sunk it while attempting to dive. Thereafter, it set out in an unsuccessful search for survivors However, there are no reports of losses or damage to British submarines in that area and in that period. The Sciesa docked in Taranto on October 8th.

On October 30th, it left Taranto but had to reverse course and return the next day, due to a mechanical breakdown.

On November 3rd, it left port with 85 tons of ammunition, arriving in Tobruk three days later. Around four o’clock in the afternoon of the same day, while unloading ammunition, it was attacked by planes and hit by three bombs: 5 officers and 18 non-commissioned officers and sailors were killed, the submarine was run aground to prevent its sinking. This was a sign of the desperate need for supplies since submarines were usually unloaded only at night.

The wreck of the Sciesa in Tobruk ℗

On November 12th, in the run-up to the fall of Tobruk to the British, the wreck of the Sciesa was mined and blown up. In 1946, the wreck was resurfaced by an Italian salvage company and tugs moved the boat to Taranto where it was sent to the scrapyard.

R. Smg. Antonio Bjamonti

The Antonio Bjamonti  was the former Yugoslavian submarine Smeli of the Osvetnik class. Built by the AC de la Loire shipyard of Nantes, France, it was lunched December 1st, 1928. The Smeli was captured by Italian forces at the Bay of Kotor in April 1942. Initially designated N2, the armament was changed, and the conning tower modified.  Due to the advanced age, old design, and shallow diving depth, when commissioned into the Regia Marina as “Antonio Bajamonti”, service was limited to training and experimentation.

A picture of the Bajamonti around 1930, when it was the Smeli

On March 8th, 1942

It carried out an ambush in the Gulf of Genoa along with the submarine H 6, another aging submarine, returning to La Spezia without having identified any enemy ships.

From November 8th through 10th, 1942

The Bajiamonti carried out another defensive mission in the Ligurian Sea and four days later it made another one off Ajaccio, but in both cases there was no sighting of enemy ships

At the proclamation of the armistice, it was under maintenance in La Spezia and therefore, unable to leave port; it was scuttled there 9 September 9th, 1943 to avoid capture by the Germans.

R. Smg. Ammiraglio Millo

The Ammiraglio Millo was an oceanic submarine of the “Ammiragli” class. Built by the CRDA shipyard of Monfalcome, it entered active service on May 1st, 1941. From May to October 1941, it was engaged in crew training becoming fully operational on September 15th. Due to its large size, it was used to transport supplies rather than the original design as ocean rader. The “Ammiragli” class was designed to navigate from Italy to Italian Somalia around the African continent without stopping.

The submarine Millo

On November 21st, 1941, it sailed from Taranto for the first mission to transport 138 tons of gasoline cans and 6.8 tons of anti-tank ammunition boxes to Derna. The Millo arrived in the Libyan port on the evening of November 23rd, unloaded, and departed on the morning of November 24th, arriving in Taranto two days later. Unloading took usually place at night to avoid British aerial attacks which were common and precise.

Other missions of this type took place on November 30th (Bardia and Benghazi), December 23rd (Tripoli) and January 26th, 1942 (Tripoli). While returning from this last voyage and near the coast of Libya, the boat was the target of an air attack with bombs but escaped unscathed. In all, on these four transport missions, the Millo carried 365.2 tons of fuel, 167 tons of ammunition, and 91 tons of supplies.

On March 6th, 1942, the boat was deployed southeast of Malta as part of Operation V5, protecting an Italian convoy carrying supplies bound for Libya. The Millo, along with other submarines, was to attack any surface units that had departed from Malta to attack the convoy. Six days later, finding no enemy ships, it returned to base.

At 01.23 PM on March 14th, the Millo was navigating off Cape d’Armi (Motta San Giovanni, Calabria) and zigzagging on the surface heading towards Taranto to return to base. There, it was sighted by the British submarine H.M.S. Ultimatum (Lieutenant P.R.H. Harrison) under a waning moon. The British captain launched a spread of four torpedoes: two of the weapons hit respectively amidships and aft of the turret, causing the sudden sinking of the Millo in position 38°27′ N and 16°37′ E. Images of the wreck, found in 2005, would suggest a single hit to the bow, not aft. The official report of Liutenant Harrison reads:

1255 hours – Sighted the conning tower of a submarine bearing 270°. Range was about 8000 yards. Started attack.

1319 hours – Fired four torpedoes from 2200 yards. Two hits were obtained and the submarine was seen to sink.

1325 hours – Surfaced and picked up fourteen survivors. These included four officers and ten ratings.

1402 hours – Dived and withdrew from the area. In the evening Lt. Harrison decided to return to Malta to land the Italian survivors.

The second explosion was probably one of the Millo’s own torpedoes going off. It should be noted that Ultimatum went undetected by the Millo for 24 minutes.

Officially, the Italian skipper, Commander Vincenzo D’Amato, two other officers and 52 non-commissioned officers and sailors were lost with the submarine (some sources indicate a total of 58 victims), while the second lieutenant commander Marcello Bertini (who after the war wrote important manuscripts on Italian submarines in the Mediterranean for U.S.M.M., the historical office of the navy) three other officers, two non-commissioned officers and eight sailors were rescued and captured by the Ultimatum. A last survivor, electrician Sergeant Lingua, was rescued by a boat which had witnessed the sinking.

As mentioned, the wreck of the submarine was found in September 2005, lying on its left side, at a depth of between 65 and 72 meters.
